Unexpected Giant Right Coronary Artery Aneurysm Diagnosed by Computed Tomography Angiography in the Emergency Department

open access: yesJournal of Clinical Ultrasound, EarlyView.
3D Volume Rendering coronary CTA reconstruction showing a giant thrombosed aneurysm of the proximal right coronary artery ABSTRACT Giant coronary artery aneurysms (GCAA) are usually defined as diameter > 8 mm or > 400% of the adjacent normal segment; they are very rare (reported prevalence ≈0.02%).

Resilience and Brain Changes in Long‐Term Ayahuasca Users: Insights From Psychometric and fMRI Pattern Recognition

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Ayahuasca is an Amazonian psychedelic brew that contains dimethyltryptamine (DMT) and beta carbolines. Prolonged use has shown changes in cognitive‐behavioral tasks, and in humans, there is evidence of changes in cortical thickness and an increase in neuroplasticity factors that could lead to modifications in functional neural ...

The Sense of Smell (SoS) Atlas: Its Creation and First Application to Investigate COVID‐19 Related Anosmia With a Comprehensive Quantitative MRI Protocol

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background The loss of smell (anosmia) has been noted in numerous diseases, including COVID‐19. Inflammatory and microstructural alterations are possible underlying mechanisms of anosmia in COVID‐19. However, no atlas exists to study olfaction and the associated tissue property changes.

Chronic atrial and intestinal dysrythmia syndrome: A late‐onset intestinal pseudo‐obstruction and cardiac dysfunction due to an SGO1 mutation

open access: yesJPGN Reports, EarlyView.
Abstract Objectives Pediatric intestinal pseudo‐obstruction (PIPO) is a rare, heterogeneous, and severe gut motility disorder. In 2014, Chetaille et al. described chronic atrial and intestinal dysrhythmia (CAID) syndrome associated with a recessive SGO1 mutation (p.Lys23Glu) linking it to both intestinal pseudo‐obstruction and cardiac dysrhythmia. This

Overview of Diagnostic Ultrasound Safety

open access: yesJournal of Ultrasound in Medicine, EarlyView.
Ultrasound is widely regarded as a safe imaging modality; however, emerging ultrasound‐based techniques—such as shear wave elastography and contrast‐enhanced ultrasound—operate with varying acoustic output parameters that may approach or exceed traditional diagnostic limits. As these technologies are increasingly integrated into human research studies,
